980-Type

The LPM will stay certified if it is operated at the maximum rating, for brief periods. Exposure to maximum ratings
for extended periods can adversely affect device reliability.

The 980-Type Pump Laser Module is a precision, high-performance, ultrahigh-reliability lightwave component that provides high output power light, in the 980 nm range. The 980-Type Pump Laser Module is comprised of a single-mode laser diode, PIN backfacet monitor, microlensed single-mode fiber, and a Fiber Bragg Grating (FBG) for improved stability, all encased in a specially designed 14-pin, oxygen free, butterfly package.

The 980-Type Pump Laser Module is capable of providing a wide range of output power in the 974 nm to 984 nm wavelength range for erbiumdoped amplifier (EDFA) system application. The pump laser module is designed and individually certified for high-reliability operation and long-term life expectancy. The 980 nm InGaAs laser chip utilizes a ridge guide design for high performance and reliability. Chip and facet parameters are optimized for stabilized optical coupling and efficient pumping of the EDFA. The laser package design also includes a microlensed single-mode fiber and a planar InGaAs PIN back-facet photomonitor assembled in a modular organic-free hermetic package. Laser welding technology is used for critical joints to achieve long-term stability. Data is archived for at least ten years. Each module is fully characterized and traceable. Long-life performance and reliability are ensured through extensive steps of burn-in, overstress, and power aging. The 980-Type Pump Laser Module is available with a typical power output range of 20 mW to 70 mW.
